Abstract

The PerFactory prototyping machine manufactured by EnvisionTec GMBH uses the photo polymerisation principle. Unlike SLA, it uses light instead of high cost laser, which makes it commercially attractive. The strength of material is major issue while exploring possible direct use of prototypes as component. This paper attempts to set-up and validate Finite Element Analysis (FEA) work in 'COSMOS' software for prototyping process. This can be used later on for stress analysis of other prototypes made using the PerFactory process. Material data were obtained by tensile tests of specimens considering its directional properties relating to interlayer adhesion. Results of FEA were validated against photo-elastic analysis and physical test of various shaped prototypes.
